Most of what I post falls into the category of "Something that should be working but isn't and how to fix it." -- all in the hope that someday I'll save someone some aggravation. Some of what I post, however, is just me being me!
Hitting something with a hammer often feels good but does nothing useful. Here's one case where it actually helps. On my 2004 Ford Explorer the alternator light came on. I brought it to the auto parts store and they put a volt meter on it. The alternator needs to put out a voltage that is higher than the battery's full charged voltage in order to properly function - somewhere in the 14 volt range. Mine came in low - probably below 13.5 volts. So the guy at the auto parts store took a rubber mallet to the alternator and just briefly, for a period of 10 seconds or maybe less the voltage jumped up into the normal range before falling back to where it was before. This confirmed the diagnosis of a bad alternator in general and worn brushes in particular. The brushes are spring loaded, are located in the are a wearable item and must make contact with the fixed part of the alternator. Tapping the alternator with the hammer temporarily changes spatial relationships between the brushes
Help, I'm composing a message in Thunderbird, I've pasted information in the form of a table, and I can't get out! Even information that does not appear to be a "table" may in fact have the HTML attributes of a table. Once you paste that info into a Thunderbird message no amount of mousing, tabbing, or other standard UI type manipulations will get you "out" of that table and allow you to add more information to the message you are composing. Have a look at this Mozilla Bug #535475 . The workaround therein provided is surprisingly easy. Select the entire text with Menu | Edit | "Select All". Menu | Insert | HTML to get an HTML editing window. Add a "<BR>" HTML element where it is needed (typically before or after the table). Continue creating your message having freed yourself from the table that had previously constrained you.
